7N1533 is (or was originally) a 3306 engine arrangement for an 81V-prefix 140G motor grader built some time between October 1978 and March 1980. Before & after those dates the engine Arrgt Numbers were different.Can't find anything on a 7N1533 arrangement.
Odd that it would be a PC engine
For a D7F installation the original 3306 engine Arrangement Number was 2P6806 for engines with S/N up 3N18568 (tractor S/N 94N5192-7184) and 6N0484 in engines with S/N above 3N18569 (tractor S/N 94N7185-Up).
So what the OP has could easily be a Frankenmotor....... who knows how it has been "altered" to install it in the D7F.?
Differences between the 7N1533 and 2P6806/6N0484 include (but not limited to) the crankshaft, piston/rod group, rear gear group, & cylinder head/valve mechanism.
I fear that a can of worms may have just been opened.
